CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 624,556, dated. May 9,1899.

Application filed March 11 1899- Serial No. 707,265. (No model.)

To (0Z5 whom it may concern:

Be it known that 1, JOHN W. SMITH, a citizen of the United States,residing at Columbia, in the county of Columbia and State of Florida,have invented a new and useful Car- Truck, of which the following is aspecification.

This invention relates to car-trucks; and the object of theinvention isto providealight and strong device of this character and which can bemanufactured at a low cost and from standard and not special or pressedmetal work.

With these ends in View the invention consists in the novel combinationof elements and in the construction and arrangement of parts, which willbe hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated thepreferred embodiment thereof in the accompanying drawings, forming apart of this specification, and in which Figure l is a plan View of aportion of a cartruck constructed in accordance with the invention. Fig.2 is a side elevation of the same. Fig. 3 is a cross-sectionalelevation,the section being taken on the line 3 3 of Fig. 1 and lookingin thedirection of the arrow. Fig. 4 is a sectional elevation, thesection being taken on the line 4 4 of Fig. 1 and looking in thedirection of the arrow.

Like characters denote like and corresponding parts in each of theseveral figures of the drawings.

In the drawings I have deemed it necessary to simply show one-half ofthe truck constituting the invention, and said truck includes in itsconstruction a side frame A, having at its opposite ends pedestal-spaces2, of box-like formation, in which the usual axle-boxes are disposed,and the pedestal-frames,hereinafter more particularly described,entirely surround said journal-boxes (not shown) and are braced in sucha manner as to produce a thoroughly staple structure capable ofwithstanding the severe strains to which apparatus of the presentcharacter are ordinarily subjected.

The side frame A includes inits construction a longitudinal channel beamor iron 3,

constituting the main member thereof and of these braces are riveted atdifferent points,

as at 9, to the under side of the web of said channel or beam at pointsadjacentto the opposite end of the latter.

The rivets 9, which connect the U-shaped braces and main channel-iron,also extend through the longitudinal flat plate 10, which extends fromone'pedestal-frame to the other, as will be obvious, and which tends tofurther strengthen the structure, and this plate has an inward extension12, against which and substantially at its middle the outer end of thetransorn plate 13 fits, said plate being secured in place by aseries ofrivets, as 14, in alinement with each other and passing through the twoparts.

The pedestal-frames are further strengthened by a brace 15, ofchannel-iron, which is located above the lower ends of the interior,braces 6 and 7 and which is bent downwardly at its opposite ends, as at16 and 17, respectively, and at right angles tothe main body thereof.These downwardly-bent portions fit against theinner legs of the U-shaped braces 6 and 7, the parts being secured together by rivets, as18, passing through the web of the brace or channel iron 15. A flatplate is shown at 19, this being com plemental to and in parallelismwith the upper plate 10, and said plate 19 fits against the upper faceof the web of the cross-brace 15, a series of rivets, as 20, passingthrough the two parts, and the ends of this plate sustain the T-shapedcoupling members 21 and 22, which are secured by rivets, as 23,atdifferent points in the height thereof to the inner legs or branchesof the U-shaped braces 6 and 7. A series of rivets, as 24, connect theflanges of these coupling members with the 'right-angularly-bent ends 25and 26, respectively, of the channel-beams or cross-girders 28 and 29,the flanges of the latter fitting against the inner faces of the upperand lower parallel plates 10 and 1!), respectively, and being securedtogether by rivets, as 30. The plate 13 is secured along its oppositeedges to the upper flanges of the channel-beams 28 and 29 by rivets, as31, and to the lower flanges of these beams a similar plate 32 issecured by rivets, as 34, which pass through the two parts, and theseupper and lower plates 13 and 32 overlap the plates 10 and 19.

It is apparent that instead of employing T- shaped coupling membersother-shaped devices could be substituted therefor without departingfrom the spirit of the invention, and it is likewise obvious that otherdevices than rivets might be employed to hold the parts in assembledrelation.

A cartrucl constructed as aforesaid is strong and light and is capableof withstanding the strains and shocks generally present, and it can bemanufactured from standard metal shapes, thereby obviating the necessityof constructing special beams and the like for its formation.

Changes in the form, proportion, size, and the minor details ofconstruction within the scope of the appended claims may be resorted towithout departing from the spirit orsacrificing any of the advantages ofthis invention.

Having thus described the invention, what I claim is- 1. In a car-truck,the combination with a main beam having right-angular downwardextensions, of inverted-U-shaped braces the outer legs or branches ofwhich are secured to said downward extensions, a longitudinal bracesecured to the inner branches of said U shaped braces, coupling membersconnected with the inner branches of said U- shaped braces, cross-beamshaving right-angular extensions at their ends secured to said couplingmembers, upper and lower plates secured to said cross-beams, and asecond pair of plates disposed in the spaces between saidfirst-mentioned plates and the cross-beams and overlapped by saidfirst-mentioned plates, substantially as described.

2. In a car-truck, the combination with a main beam having right-angulardownward extensions at its opposite ends, of inverted- U shaped bracesthe outer legs or branches of which are secured to said downwardextensions, a longitudinal brace having right-angulardownwardly-extendin g portions secu red to the inner branches of said U-shaped braces, coupling members connected with the inner branches ofsaid U shaped braces,cross-beams having right-an gular extensions attheir ends secured to said coupling member, upper and lower platessecured to said cross-beams, and a second pair of plates disposedbetween said first-mentioned plates and the cross-beam, and overlappedby said first-mentioned plates, substantially as described.

3. In a car-truck, the combination with a main channel-beam havingright-angular, downward extensions, of'inverted-U-shaped braces theouter legs or branches of which are secured to said downward extensionsand the cross portions of which are secured to the main portion of saidbeam, a longitudinal channel-brace having downwardly-bent rightangularportions secured to the inner branches of said U -shaped braces, crosschannel-beams having angular extensions at their ends, T- shapedcoupling members secured respec: tively to the inner ends of saidcross-beams and to the inner branches of the U-shaped braces, upper andlower flat plates secured to the flanges of said cross-beams, and asecond pair of plates disposed between said first-mew tioned plates andthe cross-bars and overlapped by said first-mention edplates,substantially as described.

In testimony that Iclaim the foregoing as my own I have hereto affixedmy signature i the presence of two witnesses.

JOHN WV. SMITH.
